Churn-dasher



PATENT JOHN E. FINLEY, OF MEMPHIS, TENNESSEE.

CHURN-DASHER.

SPECIFICATION forming part of Letters Patent No. 294,024, dated February26, 1884. Application filed August 18, 1883. (ModeL) To aZZ whom it mayconcern: I

Be it known that I, JOHN E. FINLEY, a citizen of the United States,residing at Memphis, in the county of Shelby and State of Tennessee,have invented a new and 'useful Improvement in Ohurn-Dashers; and Ihereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the accompanying drawing, forming a partof thisspecification.

My invention relates to improvements in chnrndashers constructed of across of metal with a central disk made ofthe same metal and being apart of the same. The arms of the cross of metal are set at an angle ofabout fifteen degrees. To these arms I attach sections of wood sharpenedat each end like a wedge, and made of segmental shape, so as to conformto the shape of the ordinary churn-tub, while the disk or central partof the casting or cross is perforated, to allow the fluid to passthrough the same. When the dasher is operated, the arms of the dasherbeing set at an angle of about fifteen degrees, it will revolve as itpasses through the fluid in churning. By tightening the screw the milkis forced through the angles of the dasher and through the central disk.This object is accomplished by raising and lowering the'dasher-staff.The sections of wood, being placed at an angle, cause the milk to beforced through the hub or disk and theother parts of the dasher when thesame is held stationary by the tightening of the screw.

My object isto supply a churn-dasher which requires much less power tooperate than the ordinary churn-dasher; and I attain this object by themechanismillustrated in the accompanying drawing, in which the figure isa perspective view, showing the improved dasher.

D is the staff of the dasher, to the lower end of which is attached thethimble T. E E E E represent the four arms of the cross or casting O, towhich are secured the sections of wood B B B B by means of screws 0 O.The sections of wood are secured at an angle of about fifteen degrees oneach of the four arms of the metal cross. In the center of the disk ofthis casting there is a hub, H, through the center of which passes thescrew S, which enters the staff D, so as to firmly hold the dasher inposition when the same is operated, and at the same time act as aspindle, onwhich the dasher revolves. The milk or cream is forcedthrough the central part of the cross, E E E E, and through the anglesformed by the same and the sections of wood B B B B, the sharp edges ofwhich break the globules containing the butter, which, with therevolutions of the dasher, will-hasten the process of butter-making. Theends of the casting E E E E, to which are attached the wedge-shapedsections of wood B B B B, are set at an angle of about fifteen degrees,all being set at the same angle. When the staff D is raised and lowered,as in churning, the dasher will revolve rapidly.

The dasher is constructed so as to be cheap and durable. The casting ismade of malleable iron, and is not easily broken.

I am aware that in the construction and manufacture of churn-dashersvarious revolving churndashers with perforated disks and wooden sectionsattached to the arms of the castings have been employed; but

What I claim, and desire to secure by Letters Patent, is-

The churn-dasher herein described, consisting of the casting G, havingcentral perforated hub, and provided with arms E E, having slantingends, the segmental wedge-shaped sections of wood B B, attached to saidends, hub H, screw S, and staff D, as specified.

JOHN E. FINLEY.
